Evaluate: [(40 + 5) – 32] / 9 • 2?

5 Answers

• First we do 40 + 5 = 45

  Second we do 45 – 32 = 13

  Third we get 13/18 which is the answer..

  The order of operation is:

  1. parentheses

  2. exponents

  3. multiply

  4. divide

  5. addition

  6. subtraction

  Remember the word pemdas. The first letter of each operation.

• it is evaluated in the following order : first you evaluate the brackets, then the division, then the multiplication, then the addition and in the last the subtraction.

  [(40 + 5) -32] / 9 * 2

  [45 -32] / 9 * 2

  13 / 9 * 2

  1.4 * 2

  2.8 (approx.)

• {(40 + 5) – 32} / 9 * 2 =

  {(45) – 32} / 9 * 2 =

  (13) / 9 * 2 =

  13 / 18.

• Follow order of operations:

  Do these steps from left to right

  PEMDAS is a good acronym for it

  Parantheses (and brackets)

  Exponents

  Multiplication

  Division

  Addition

  Subtraction

• solve the inner brackets first

  [(45)-32]/9×2

  =[45-32]/9×2

  =13/9×2

  =26/9

  =2.8/9
